粘液性口腔球菌(stomatococcus mucilagino-sus)是寄居于口腔的革兰氏阳性球菌。很少被证明有致病性。以前曾有过该菌引起心内膜炎、腹膜炎等的报告,但由导管感染所致败血症这是首例。患者,男,79岁,肝硬化,肝功能丧失代偿,合并上消化道出血。因少尿、血清肌酐增高,急性肾功衰竭,在右颈静脉安置了导管作透析治疗。第二天在导管抽入部位出现血肿。随后体温上升达38.8℃,取出导管后仍然发热不减。经导管和血培养确证为粘液性口腔球菌感染。作者采用的方法是:导管培养,将取出的导管以末端在羊血琼脂平板上滚动,培养结果若同一种细菌菌落>15个时判断为感染;血培养,将血平板种末胰蛋白酶水解的大豆肉汤培养基和哥伦比亚瓶(Roche septi-chek system)中培养,每天观察,持续10天,阳性结果作涂片染
Stomatococcus mucilagino-sus is a gram-positive cocci that resides in the oral cavity. Rarely proven to be pathogenic. There have been previous reports of endocarditis, peritonitis, etc., but this is the first case of septicemia caused by catheter infection. Patients, male, 79 years old, cirrhosis, decompensated liver function, with upper gastrointestinal bleeding. Due to oliguria, increased serum creatinine, acute renal failure, catheterization in the right jugular vein for dialysis treatment. The following day there was a hematoma at the catheter site. Then body temperature rose up to 38.8 ℃, after removing the catheter still fever diminished. Confirmed by ductal and blood cultures are mucoid oralococcal infections. The authors used the method is: catheter culture, the catheter will be removed to the end of the sheep blood agar plate rolling, culture results if the same bacterial colonies> 15 were judged to be infected; blood culture, the platelet end trypsin hydrolysis Soy broth and Roche septi-chek system and observed daily for 10 days with positive results as smear
